the smartest people (phds and others) will tell you to take the average. also harriet crone my great great grandmother's neighbor in transylvania said, "take the average". housewives of new jersey will say, "take the average". doing that will make you feel better but you will then have three incorrect estimates: the high, the low, and the average. good luck with that.
